Intshayelelo
Imigodi yinkqubo yokongeza iirekhodi zentengiselwano kwileja yoluntu yeBitcoin yeentengiselwano ezidlulileyo. Le leja yeentengiselwano ezidlulileyo ibizwa ngokuba yiblockchainnjengoko iyityathanga leiibhloko. Iblockchainukhonza kuqinisekisaiintengiselwano kuthungelwano luphela njengoko kwenzekile. Iinodi zeBitcoin zisebenzisa ikhonkco lebhloko ukwahlula iintengiselwano ezisemthethweni zeBitcoin kwiinzame zokuphinda usebenzise iingqekembe esele zichithwe kwenye indawo.
Ukumbiwa kwemigodi kuyilwe ngenjongo ukuba kusetyenziswe ngamandla kwaye kube nzima ukwenzela ukuba inani leebhloko ezifunyenwe suku ngalunye ngabembi-mgodini zihlale zizinzile. Iibhloko zomntu ngamnye maziqulathe ubungqina bomsebenzi oza kuthathwa njengosemthethweni. Obu bungqina bomsebenzi buqinisekiswa ngamanye ama-Bitcoin nodes rhoqo xa befumana ibhloko. I-Bitcoin isebenzisa iI-hashcashumsebenzi wobungqina bomsebenzi.
Injongo ephambili yemigodi kukuvumela i-Bitcoin nodes ukuba ifikelele kwimvumelwano ekhuselekileyo, echasene ne-tamper-resistant. Ukumbiwa kwemigodi ikwayindlela esetyenziswayo ukwazisa iBitcoins kwinkqubo: Abasebenzi basezimayini bahlawulwa nayiphi na imirhumo yentengiselwano kunye “nenkxaso-mali” yeenkozo zemali ezisandul’ ukudalwa. Oku zombini kusebenzela injongo yokusasaza iingqekembe ezintsha ngendlela yolawulo kunye nokukhuthaza abantu ukuba babonelele ngokhuseleko kwinkqubo.
Imigodi yeBitcoin ibizwa njalo kuba ifana nokumbiwa kweminye imveliso: ifuna umgudu kwaye yenza kancinci kancinci ukuba iiyunithi ezintsha zifumaneke kuye nabani na onqwenela ukuthatha inxaxheba. Umahluko obalulekileyo kukuba ukubonelela akuxhomekanga kwisixa semigodi. Ngokuqhelekileyo ukutshintsha i-hashpower ye-minener epheleleyo ayitshintshi ukuba zingaphi ii-bitcoins ezidalwe kwixesha elide.
Ubunzima
Ingxaki yeKhompyutha-Nzima
Ukumba ibhloko kunzima kuba i-SHA-256 hash yentloko yebhloko kufuneka ibe ngaphantsi okanye ilingane nethagethi ukwenzela ukuba ibhloko yamkelwe yinethiwekhi. Le ngxaki ingenziwa lula ngeenjongo zenkcazo: I-hash yebhloko kufuneka iqale ngenani elithile le-zero. Amathuba okubala i-hash eqala ngo-zero amaninzi aphantsi kakhulu, ngoko ke kufuneka kwenziwe iinzame ezininzi. Ukuze kuveliswe ihashi entsha umjikelo ngamnye, anakanyeiyanda. 'YabonaUbungqina bomsebenzingolwazi oluthe kratya.
Ubunzima beMetric
Iubunzimangumlinganiselo wendlela ekunzima ngayo ukufumana ibhloko entsha xa ithelekiswa neyona ilula inokuba yiyo. Ibalwa kwakhona zonke iibhloko ze-2016 kwixabiso elinokuthi iibhloko zangaphambili ze-2016 zibe ziveliswa kwiiveki ezimbini kanye ukuba wonke umntu ube nemigodi kobu bunzima. Oku kuya kuvelisa, ngokomndilili, ibhloko enye rhoqo ngemizuzu elishumi. Njengoko abavukuzi abaninzi bajoyina, izinga lokudalwa kwebhloko liyenyuka. Njengoko isantya sokuvelisa ibhloko sanda, ubunzima buphakama ukuhlawulela, obunokulinganisela kwesiphumo ngenxa yokunciphisa izinga lokudala ibhloko. Naziphi na iibhloko ezikhutshwe ngabembi-mgodini abakhohlakeleyo ezingafikeleliyo ezifunekayoubunzima ekujoliswe kukoiyakukhatywa ngokulula ngabanye abathathi-nxaxheba kumsebenzi womnatha.
Ibuyiselo
Xa ibhloko ifunyenwe, umfumanisi unokuzinika inani elithile le-bitcoins, evunyelweneyo ngumntu wonke kwinethiwekhi. Okwangoku le bhonasi yi-6.25 bitcoins; eli xabiso liya kuba ngesiqingatha zonke iibhloko ezingama-210,000. 'YabonaUnikezelo lweMali oluLawulwayo.
Ukongezelela, umgodi unikezelwa ngeentlawulo ezihlawulwa ngabasebenzisi abathumela ukuthengiselana. Intlawulo yinkuthazo yokuba umvukuzi abandakanye ukuthengiselana kwibhloko yabo. Kwixesha elizayo, njengoko inani labavukuzi abatsha be-bitcoins bavunyelwe ukudala kwibhloko nganye liyancipha, imirhumo iya kwenza ipesenti ebaluleke kakhulu yengeniso yezimayini.
Inkqubo yendalo yemigodi
Hardware
Abasebenzisi basebenzise iintlobo ezahlukeneyo zehardware ekuhambeni kwexesha ukwenza iibhloko zemigodi. Iinkcukacha ze-Hardware kunye neenkcukacha-manani zokusebenza zicacisiwe kwiUthelekiso lwe-Hardware yeMigodiiphepha.
CPU Mining
Iinguqulelo zabathengi beBitcoin zangaphambili zivumele abasebenzisi ukuba basebenzise ii-CPU zabo kwimigodi. Ukufika kwemigodi ye-GPU kwenza imigodi ye-CPU ingabi nabulumko ngokwezemali njengoko i-hashrate yenethiwekhi ikhula ukuya kwinqanaba lokuba isixa se-bitcoins esiveliswe yi-CPU yemigodi yaba ngaphantsi kweendleko zamandla okusebenza kwe-CPU. Ukhetho ke ngoko lususiwe kujongano lomsebenzisi ongundoqo womthengi weBitcoin.
GPU Mining
I-GPU Mining ikhawuleza kakhulu kwaye isebenza ngakumbi kune-CPU yemigodi. Jonga inqaku eliphambili:Kutheni i-GPU imigodi ngokukhawuleza kune-CPU. Iindidi ezahlukeneyo ezidumileyoizixhobo zemigodizibhaliwe.
Imigodi yeFPGA
Imigodi ye-FPGA yindlela esebenza kakuhle kakhulu kwaye ekhawulezayo yeyam, enokuthelekiswa nokwembiwa kwe-GPU kunye nokugqwesa ngokugqithisileyo kwe-CPU yemigodi. Ii-FPGAs zidla ngokutya amandla amancinci kakhulu anemilinganiselo ephezulu ye-hash, ezenza zisebenze ngakumbi kwaye zisebenze ngakumbi kunemigodi ye-GPU.

Imigodi ye-ASIC
Isicelo-specific isekethe edibeneyo, okanyeI-ASIC, yi-microchip eyilwe yaza yenzelwe injongo ekhethekileyo. I-ASICs eyenzelwe imigodi yeBitcoin yakhululwa okokuqala ngo-2013. Ngenxa yesixa samandla abawasebenzisayo, bakhawuleza kakhulu kunabo bonke ubugcisa obudlulileyo kwaye sele yenze imigodi ye-GPU ingabi nabulumko ngokwezimali kwamanye amazwe kunye nokusetha.
Iinkonzo zemigodi
Iikontraka zemigodiukubonelela ngeenkonzo zemigodi ngomsebenzi ochazwe ngokwekhontrakthi. Banokuthi, umzekelo, baqeshe inqanaba elithile lomthamo wemigodi ngexabiso elimiselweyo ngexesha elithile.
Amachibi
Njengoko besanda abasebenzi-mgodini bekhuphisana ngokubonelelwa okulinganiselweyo kweebhloko, abantu ngabanye bafumanisa ukuba basebenze iinyanga ngaphandle kokufumana ibhloko kwaye bafumane umvuzo ngenxa yemigudu yabo yemigodi. Oku kwenza imigodi ibe yinto yokungcakaza. Ukulungisa umahluko kwimivuzo yabo abasebenzi-mgodini baqalise ukuzilungiselelaamadamaukuze babelane ngemivuzo ngokulinganayo. Jonga imigodi edibeneyo kunyeUkuthelekiswa kwamachibi emigodi.
Imbali
Ileja yoluntu yeBitcoin ('block chain') yaqalwa nge-3 kaJanuwari 2009 ngo-18:15 i-UTC kucingelwa ukuba nguSatoshi Nakamoto. Ibhloko yokuqala yaziwa ngokuba yiibhloko yegenesis.Ukuthengiswa kokuqala okurekhodiweyo kwibhloko yokuqala kwakuyintengiselwano enye ehlawula umvuzo we-bitcoins entsha ye-50 kumdali wayo.
